IMPROVEMENT IN CHURNS.

Specification forming part of Letters Patent No. 48,469, dated J une 27, 1865.

-cation- Figure 1 beinga side elevation of achurn provided with my improvements; Fig. 2, a vertical section thereof, in a planeindicated by the line a' .'r, Fig. l; Fig. 3, a bottom view of the churn-dasher.

Like letters designate corresponding parts in all of the figures.

Let A represent the body of the churn, which may be a square boX, as shown, with a closelytting cover, a. On one side is secured a standard, b, Fig..l, extending upward a proper distance to pivot an operating-lever, B, to it. My first improvement consists in a convenient means for connecting the dasher-rod c with the lever B, so as to allow the rod always to work freely in a straight line in the center of' the churn, and to enable the rod and lever to be quickly and easily disconnected, when desired,for gaining admission to the inside of the churn. This device is composed of a notched pin, D, passing through a long curved slot, e, in the lever, and a hole in the dasher-rod, and of a spring-catch, f, resting in the notch (Z of the pin D. The slot e allows the pin D and dasher-rod c to play laterally, so as to keep the rod centrally in thehole through the cover a of the churn-body. The spring-catch f and notch d in the pin hold the pin securely in place, while the spring-catch can be lifted in an instant from the notch and the pin withdrawn from the lever and rod, when the lever is ready to be detached from the rod, and to be swung back out of the way, and the cover a can be drawn off from the rod. The whole are just as readily replaced again.

My second improvement consists inl an improved dasher, C. Itis composed of a central box, about half illin g the transverse space of the churn-body, having vertical sides h h h h, a rim, g, at the top, reaching close outto the sides of the churn-body, and having its bottom closed by two swinging lids, G G, all substantially as shown in Figs. 2 and 3. The lids G G swing and open downward, as indicatedby dotted lines in Fig. 2, and close tightly upward against `a central partition or support, t', to which the flasher-rod o is attached. The vertical sides h 7L of the dasher are perforated with holes m m m, as shown in Fig. 2. As the dasher moves up and down the rim g closes the space of the churn-body, thereby forcing the cream to pass through the dasher itself. In ascending its bottom lids openV downward and allow a portion of the cream to dow through, the currents thereof crossing and intermingling, so as to produce'iucreased agitation of the cream, and this passage, together with the holes m m m in the vertical sides h L h lL of the dasher, enables the dasher to be raised more easily than it descends-an effect which is to be desired, because lifting the dash-` er is more wearisome labor than forcing it down, the weight of the dasher impeding the one but assisting lthe other movement. In the descent of the dasher all, or nearly all, of the cream is forced in through the holes m 'm m of the dasher sides. These contracted passages operate effectually on the cream, and the direction of the streams being horizontal there is no splashing up and leaking ot' the cream at the top of the churn.

I I disclaim the use of hinged wings or lids applied to ch urn-flashers, such having been before employed; Abut What I claim as my invention, and desire to secure by Letters Patent, is

1. The combination of the notched pin D in the lever-slote'and dasher-rod c with the springcatch f, for the purposes herein specified.

2. The construction of the dasher C, with its vertical perforated sides h h, close rim g, and close swinging lids G G, substantially as and for the purpose herein set forth.

The above specification of my improved churn signed by me this 7th day of January, 1865.
